Giuliana Rancic Dances in a Onesie Outfit to Make Baby Duke Laugh

Giuliana Rancic will do anything to make her little boy Edward Duke Rancic smile -- even if it leads husband Bill Rancic to declare her crazy! Donning a hilarious gray adult-sized onsie outfit on the Tuesday, July 23 episode of the couple's Style reality series Giuliana & Bill, the first-time mom, 38, attempts to show off her dance moves in order to impress Duke, 11 months.

In a joint Us Weekly interview with her husband July 16, Giuliana hinted she was considering an Italian-themed fete. "He's half Italian, so maybe we'll do an Italian theme. That'd be cute. It'll be like The Godfather," she told Us, referring to the 1972 film that follows a New York City-based Italian family with Mafia ties. Bill, however, wasn't into it. "That's good role model, someone to look up to: [crime boss] Michael Corleone!" he joked of the character portrayed by Al Pacino. "It is not a good idea!"
